In this embodiment, the second step surface 32b can ensure that the hook 341 does not retreat into the going groove 324 after sliding into the hanging groove 322; the third stepped surface 32c functions such that even if the elastic force of the lock member 34 is insufficient or the relative movement of the hook 341 and the slider 32 is too fast, the hook 341 can be guided to the forward-movement groove 324 by the third stepped surface 32c without sliding from the common groove 323 into the return-movement groove 325.

Further, the height of the bottom surface of the trip groove 324 is gradually increased from the back to the front; the height of the bottom surface of the return groove 325 is gradually increased from front to back.

In this embodiment, since the free end of the hook 341 slides against the bottom surfaces of the common groove 323, the going groove 324, the hanging groove 322, and the returning groove 325, the height of the groove bottom gradually changes to ensure smooth sliding, and the height gradually increases in opposite directions to ensure the total height change of the free end to be kept at a minimum, so that the free end of the hook 341 can contact the groove bottom with an average minimum elastic force and be kept in the above-mentioned respective grooves.

Further, a baffle 313 is disposed at the rear end of the sliding slot 311 on the base 31, the first elastic member 35 is a compression spring, and one end of the first elastic member 35 abuts against the baffle 313 and the other end abuts against the slider 32.
